I have a 1902 vintage Marlin 94, 38-40, 24" oct. barrel and I would like to put another ejector spring in it.Anyone know where I can get tear down instructions? I can probably figure it out without them, but they are nice to have.
Also, anyone have a ball park idea of what it would cost to have this gun rebored to 44-40?

Go to Marlinowners.com.There are a lot of guys on there that know all about Marlin lever guns.If they can not answer your question they can point you in the right direction to find the answer.

Thanks,Will do.

Thans.Got that one already with my 94, 44 mag. I need an older one.However,I did take the lever off last night and wa sable to get tehe ejector out. Now i need to find a new one.
Thanks again

Got on the Marlin site and was led to Wisners nad haev found a ejector.
I was advised to not bore out to 44-04 as it would come back a 44 mag bore which would put it slightly bigger than is required.
